Patent GB-1028206-A (GB)
Title: Improvements in malting
Inventor: PINNER BRIAN CHARLES
Filed: 1963-09-26
Abstract: A bed of grain in a pneumatic matting is cooled by passing a flow of humidified cooling air through the bed without turning, mixing or otherwise moving the grain, and the direction of air flow through the bed is frequently reversed.  The rate of air flow is greater than is usual in pneumatic maltings and preferably is not less than 600 cub.ft./ton/ minute.  The direction of the air flow may be reversed at regular intervals by a time switch. Alternatively, the flow is controlled by a thermostatically operated switch which acts to shut off the flow of cooling air when the temperature of the grain bed falls below a predetermined level and to restart the flow when the temperature rises above a second predetermined level, the direction of the flow being reversed each time it is restarted. Examples are directed to the flow through beds of grain of humidified air at temperatures of 50 DEG F. and 57 DEG F., respectively.

Title: Mounting a crystal for slicing
Inventor: CROCKER NORMAN JOSEPH
IPC: H03H3/02
Filed: 1958-12-04
Abstract: 878,243. Moulds for mounting crystals. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 25, 1959 [Dec. 4, 1958], No. 39180/58. Class 87(2). [Also in Group XXIII] A method of mounting a crystal, e.g. a semi-conductor crystal, for slicing, e.g. by a diamond saw, comprises locating a crystal with respect to a mould, the internal surface of which is provided with projections or recesses, clamping the crystal in its located position by means of clamps so that a portion of the crystal depends below the clamps, pouring a plaster into the mould so as to cover said projections or recesses and a portion of the crystal but not the clamps, allowing the plaster to set and then removing the clamps. Alternatively or in addition, inserts can be positioned on the projections or in the recesses in the mould prior to pouring the plaster and these inserts will become integral with the casting, when set, at predetermined locations. A semi-conductor crystal is orientated and located by some suitable means with respect to a reference surface such as a flat metal table so that the direction in which it is to be sliced is at say 90 degrees to the table, and the crystal is then clamped by small G clamps. The lower half 1 of a mould is then placed on the table under the crystal ; this half comprises an aluminium tray with a removable side 3 and includes pegs 8 secured to the base of the tray on which are positioned locating plates 6, 7. Plaster, e.g. a dental type plaster, is poured into the tray until its level is just below the clamps. When the plaster is nearly set its surface is scored to provide a key for a further layer of plaster and when it has quite set the clamps are removed from the crystal which is now firmly located by the plaster with respect to the plates 6, 7. The upper half 2 of the mould is fitted over the lower half being located thereon by pegs 9 and recesses 10, and a further layer of plaster is added to cover the crystal completely. When the plaster has set, the top mould half 2 is lifted and the side 3 of the lower mould half 1 removed so that the plaster casting can be detached. The latter includes the plates 6, 7 containing recesses which can engage pins on the table of a slicing machine.

Abstract: 1,103,847. Linkwork. SOC ANON ANDRE CITROEN. 7 Sept., 1966 [15 Sept., 1965], No. 39959/66. Heading F2K. [Also in Division F4] A motor vehicle has a first pair of fixed head lamps and a second pair of pivoted headlamps which are connected to the steering mechanism in such a way that the lamp on the inside of a given turn is caused to pivot through a larger angle than the lamp on the outside of the turn. As the turn becomes sharper the angle between the pivoted headlamps increases and their rate of pivoting decreases. In one embodiment, each pivoted lamp has a rearwardly inclined pivot-pin 18 biased in one angular direction by a spring 19 and carrying a pulley 17 around which is wound a cable 16 connected to a rod 11 pivotally linked by a further rod 13 to a plate 10 fixed to a steering lever 8. When, as shown in Fig. 7, the lever 8 is rotated in a clockwise direction about its pivot 9, the rod 13 bears against a stop 15 and the rod 11 is moved by the pivot 12. During anticlockwise rotation, however, the rod 13 leaves the stop 15 and the rods 11, 13 are moved by the pivot 14 which is nearer than the pivot 12 to the pivot 9. In a modification, the pulley 17 is replaced by a cam (20, Fig. 9, not shown), and the cable (16) is connected directly to the plate (10). In a further modification (Figs. 10-12, not shown), an arrangement similar to that shown in Fig. 7 is mounted on the pivot-pin 18.
